Hello,
Thank you for posting in the Microsoft community forum.
I don't know much about the Syncthing service. May I know if you changed user permissions when configuring the service?
Notice the user who created the task needs to be a member of the administrators group. According to your description, the "prav" account should be the account with which you log in to your device. You can check further in local users and groups.
Here is a step:
- Right click on the Windows icon and select "Computer Management"
- Navigate to System Tools > Local Users and Groups.
- Check that the "prav" account has been added to the "Administrators" group.
You mentioned that there were other accounts such as gmail id when you selected the account, which may be that the system saved user records when you used the relevant services before. You can also remove it from users and groups if it is no longer needed.
I hope this helps.
Best regards
Jacen
